Wrong error reported while scanning records when query contains several ordering fields

[NVO777]

Error reported while scanning such query: SELECT id, req_primary_fields FROM audit_log ORDER BY created_tstamp DESC, id ASC LIMIT 10 OFFSET 0, Error = Scan error on column index 1, name "req_primary_fields": converting NULL to string is unsupported

No error should happen here, because SELECT COUNT(id) FROM audit_log WHERE req_primary_fields IS NULL returns 0

Not sure would it be possible to reproduce it, but i attached code and log and You can analyze it
